no, they don’t. I grew up next door to a state park with a small river. my sibs and I ran wild down there all summer collecting you name it–tadpoles we would raise into frogs and let go, monarch and other caterpillars we would watch become butterflies and moths… we climbed trees and built forts and ran all over the path system. it was awesome. nowadays you have to fear more for your kids and they have too many other distractions. my kids turned out ok but they missed out on a lot of that. progress, you know.
